Abstract

PURPOSE: To make hands matching of that time easy by making the feed speed within 10 minutes before and after the display time before fast feed at a low speed at the time of fast feed.
CONSTITUTION: In ordinary hand operation, a fast feed switch S2 is turned ON and a counter 5 is set in the state where there in no input. A changeover circuit 3 outputs 1/60 Hz of a frequency divider 2 to a display device at this time, and the wacth operates as a 1-minute hand operation watch. When the fast feed switch is operated, S1 goes ON and S2 cooperating thereto goes OFF. Then, a counter 5 receives the OR output of 1 Hz or 1/60 Hz signal and starts counting. The counter 5 is fitst set at 9 in its count number ot control the output of the changeover circuit 3 so that it becomes 1Hz while the count number is between 0 to 8, 10 to 20, thus the feed speed is lowered for 10 minutes before and after the display time. While the counter 5 is between count numbers 21 to 719, the output of the changeober circuit 3 is controlled to 128 Hz, thus fast feed is made. On the other hand, when the count number is 9. The changeover circuit 3 is controlled to make its output 1/60 Hz.
